' 7 15003 Lemon i1 Application filed lune l, 1928, Serial mtmm "Renewedmcenrber ,8, 19 0. f r j v The present inventionrelates to improvements in door latches, the same contemplating the provision of a door securing means capable of being operated with but little 5 effort on the part of the operator, and which can be manufactured and'sold at low cost,

has for one of its most important objects the provision of latch means of this nature which and yet be of such strong and durable construction as to reduce any liability that the same will be easily broken or otherwise impaired. v

Another object is to provide a latch construction including a spring projected bolt,

wherein the spring employed for projecting the bolt is accessible to the hand of the operator, so that by effecting-a'pressure against the spring, the bolt will be retracted.

After reading the following specification and'claim, other important objects and advantages of this invention will become apparent.

In the drawings:

Figure 1 represents a fragmentary portion of a door structure with the present invention shown associated therewith and in door securing position.

Figure 2 represents the fragmentary sectional view of a door in closed position with respect to the jamb portion of the doorway showing the leaf springs for normally maintaining the slidable bolt projected outwardly.

Figure 3 is a sectional view, through the door and jamb'portion of the door way, showing a top plan view of the ,slidable bolt member.

Figure 4 is a vertical sectional view through .a portion of the door and latch mechanism,

to each sideof the door.

with an: inwardly andghorizontally disposed .slotl, in which the latch plate lorgbolt'2 is Sadat. I

This zla tchplate is provided at its inner end with outwardly diverged arms 3 which pro- '55 je'ct' beyond opposite sides of. the doonLA leaf-spring 4 is secured to each side ofthe door. Each of these leaf springs is secured atone end to the door, while its opposite end} is connected toone of vthediverged arms 3 vposition over the open .side of the slot 1 formed 'inthe door.1 A rivet Ssecures'the' elongated foot portions :of .thehandles 5 against opposite sides of the .door and in a position to partially close the open sides of the .slots.1,.and provide a guideway for the sl-idablelatch plate 21. :The short pieces of v V "the handle are disposed ag'ainst thefixed end 7 portions of the leaf springs 4; and are then secured in place by a suitable bolt 9 extending through the door and tightly binding the "end portions offlthese elements thereagainst. so

.Thelatch plate2'is preferably formed with abevelledfiend lOand .an upstanding lug 11 formedthereon. The ends of the feet 7 are preferably connected by a jamb .p1ate12, in which. an opening is formed,to permit the projectionof the bevelled end 10 ofthe latch plate to project. 7 i j V A'T-member 13 is formed at oneend with.

.aloopfl t anda .notch immediately inwardly from this' 'loo ped end. The shank of the key cc is arranged throughregistering openings in the feet, portions 7 and the door A, immediately above the latch plate 2.

' The free .end of the key may be bent or enlargedto prevent the displacement there of. By,rotating' the key, the same may be disposed'in the'position shown inFigure 4E, whereby'the latchplate '2 will be free to move without limitation. However, the key is turned to a right angular pos1ti'onin use "we spect to'its disengaged position, the same thereof is secured to the inner end of the latch will 'prevent'the inward motion of the latch bolt, said leaf spring being normally spaced plate, if the lug 11 thereon is disposed outfrom the intermediate portions of the said wardly from the key, while on the other hand, handle so that by drawing the leaf springs ed outwardly.

A U-shaped plate 16 is secured to'the j amb edge portion of the wall B, so thatits bight Y portion will be in opposed relation to the con if the key is turned to the engagingposition toward the handles, the latch bolt will be rewhile the plate is in retracted position, the tracted. key will prevent the bolt from being project- I p In testimony whereofl aflix my si nature.

v necting structure 12 of the handles 5'. "The f bight portion of the U-shaped plate is formed; 1 a with an opening 17 registering with an opening 17 formed in the edge of the wall. Obviously, when the latch plate is in projected position, the bevelled end 10thereof is seated Within the socket 18 of the wall 13. The, leg portionsofthe plate 16 are secured to the opposite sides of the wall B by suitable bolts 19. A stop plate 20' is secured to the inner side of the wall'and is'adapted to project at one end beyond the edge thereof, to afford astop for .the door. I} I It will be noted that when theparticular spring 4 is drawn toward the corresponding handle 5 thelatch plate 2 is retracted and permits the closure to be opened. Of course, 'this latch plate cannot be retracted until'the key 13 has been properly set so that the lug 11 will pass through the notch 15 in the key stem. Promptly upon release of the spring 4, the same will assumeits projected position and be ready to snap into position in the socket of the door frame when the 'door is swung to closed position.

While the preferred form. of the invention is disclosed in the accompanying draw ings, changes in the shape, size or material, in the construction of this 'inventlon may be resorted to, withoutdeparting from the spirit of the invention or the scope of the appended claim.

Having described the invention, what is claimed as new is: j p

A closure fastener comprising a pairof handles constructed of a single strip of material, said strip being bent at its intermediate point to form a substantially 'U-shaped portion for engagement against the j amb portion of the closure, each end portionofi; said strip being curved outwardly from the olo 7 sure with its extremity secured to the corresponding side of the closure, the bight portion of the said strip being provided with an opening, a latch bolt slidably disposed within the confines of the U-shaped portion ofthe strip and being slidable through the opening in the bight portion thereof, a pair of leaf spring elements, one at each side of the closure, and each being interposed between one side of the closure and the corresponding handle portion, one end of each leaf spring being secured to the free end of the corre spendingv handle, while the opposite end H I v
